Propagate errors up when columns aren't found

[jonhoo]

Try installing this recipe:

CREATE TABLE Article (id int, title varchar(255), PRIMARY KEY(id));
CREATE TABLE Vote (article_id int, user int);
CREATE VIEW VoteCount AS SELECT Vote.article_id, COUNT(user) AS votes FROM Vote GROUP BY Vote.article_id;
QUERY ArticleWithVoteCount: SELECT VoteCount.id, VoteCount.votes AS votes FROM VoteCount WHERE VoteCount.id = ?;

You'll see the server crash with this error:

thread 'worker' panicked at 'tried to look up non-existent column Column { table: Some("VoteCount"), name: "id", function: None, aliases: [] } on node "VoteCount" (columns: [Column { table: Some("VoteCount"), name: "article_id", function: None, aliases: [] }, Column { table: Some("VoteCount"), name: "votes", function: None, aliases: [] }])', server/mir/src/node.rs:283:29

This should instead be communicated as an error to the client who tried to install that recipe.
